The planting area of macadamia in China accounted for more than one third of the world’s planted area. The lipid compositions, minor components, and antioxidant capacities of fifteen varieties of macadamia oil (MO) in China were comparatively investigated. All varieties of MO were rich in monounsaturated fatty acids, mainly including oleic acid (61.74–66.47%) and palmitoleic acid (13.22–17.63%). The main triacylglycerols of MO were first time reported, including 19.2–26.1% of triolein, 16.4–18.2% of 1-palmitoyl-2,3-dioleoyl-glycerol, and 11.9–13.7% of 1-palmitoleoyl-2-oleoyl-3-stearoyl-glycerol, etc. The polyphenol, α-tocotrienol and squalene content varied among the cultivars, while Fuji (791) contained the highest polyphenols and squalene content. Multiple linear regression analysis indicated the polyphenols and squalene content positively correlated with the antioxidant capacity. This study can provide a crucial directive for the breeding of macadamia and offer an insight into industrial application of MO in China.

The pyrochloresA2B2O6O′ attract much attention because of their physical properties. Several models which relate chemical compositions of ternary pyrochlores with lattice constants have been proposed. Analysis of these models shows that some of them are statistically inadequate and cannot be used. Statistical models to predict lattice constants of ternary pyrochloresA2B2O6O′ have been derived using multiple linear regression analysis.

First Time

The unambiguous electronic absorption spectra of HgX42−(X = Cl, Br, or I) in methanol have been determined for the first time. The spectra were resolved into their component Gaussian bands, and assigned using a correlation diagram for Td symmetry. The effects of second-order spin–orbit coupling account satisfactorily for the observed band intensities and splittings. The formation constants, K4, as a function of ionic strength were computed over the complete spectral range by multiple linear regression analysis and were, extrapolated to infinite dilution, 0.4 ± 0.1 for Hgl42− and HgBr42−, and 5.7 ± 0.2 for HgCl42−. Significant cation effects were observed upon the spectra of HgX2 with added X−, and may partially be explained in terms of the extended Debye–Hückel equation. Key words: electronic absorption spectra, mercury(II) halide complexes, formation constants, ionic strength, Gaussian band analysis.

Background. The cyclooxygenase- (COX-) 2/microsomal PGE-synthase- (mPGES-) 1/PGE-receptor- (EP-) 4 axis could play a key role in the physiopathology of abdominal aortic aneurysm (AAA) in humans. In this study, we investigated the influence of cardiovascular risk factors on the expression of thePGE2pathway in human AAA.Methods. Aortic(n=89)and plasma(n=79)samples from patients who underwent AAA repair were collected. Patients were grouped according to risk factors. COX-isoenzymes, mPGES-1, EPs,α-actin, and CD45 and CD68 transcripts levels were quantified by QRT-PCR and plasmaPGE2metabolites by EIA.Results. Current smoking (CS) patients compared to no-CS had significantly higher local levels of mPGES-1(P=0.009), EP-4(P=0.007), andPGE2metabolites plasma levels(P=0.008). In the multiple linear regression analysis, these parameters remained significantly enhanced in CS after adding confounding factors. Results from association studies with cell type markers suggested that the increased mPGES-1/EP-4 levels were mainly associated with microvascular endothelial cells.Conclusions. This study shows that elements of thePGE2pathway, which play an important role in AAA development, are increased in CS. These results provide insight into the relevance of tobacco smoking in AAA development and reinforce the potential of mPGES-1 and EP-4 as targets for therapy in AAA patients.

Purpose/objective: The purpose of this research is to investigate the influence of the 2008 xenophobic events on the structure of earnings of street traders in inner-city Johannesburg and to provide recommendations to policymakers.Problem investigated: The xenophobic events of 2008 are well documented, but absent from the literature is the potential influence on the earnings of foreign street traders. This study investigates this influence through analysis of data from before and after the events.Design and methodology: The study applies an exploratory cross-sectional research design using data from three different samples. Mann-Whitney and Chi-squared measures are applied together with exploratory multiple linear regression analysis to generate insight into the relationships between earnings and differences by origin.Findings and implications: In 2009 the earnings structure of the sector changed. In 2008 and 2010, the earnings of foreign traders are higher, whereas in 2009 these traders earned less than local traders. It is argued that the xenophobic events might have resulted in a temporary restructuring of earnings.Originality or value of the research: This study makes a contribution through exploratory findings that document a change in the structure of earnings of foreign street traders.Conclusion: A change in the structure of earnings of foreign street traders occurred after the xenophobic events of 2008. Although association cannot ascribe causality, it is argued that this change may be related to these events.

This study aims to identify the determinants that influence the attitudes of consumers of green purchases and the willingness to pay more on green products, specifically on energy-saving lighting products. The variables studied included environmental knowledge, environmental awareness and perceived effectiveness. The sample of this study was 196 students, but out of 196 respondents after the questionnaire was distributed only 189 could be processed. Validity and reliability test results show valid values of loading factors of more than 0.4 while for reliability testing using the cronbach’s alpha criteria above 0.5 indicates reliable. Through the multiple linear regression analysis, the variables of environmental knowledge, environmental awareness and effectiveness are felt to have a positive and significant effect on the attitude of buying and willingness to pay more. Green purchasing attitudes and willingness to pay more have a positive and significant effect on green purchasing behavior. Green purchasing attitudes have a greater influence on green purchasing behavior compared to willingness to pay more.
